Sadie May has decided to start a business where she will sell a single line of high heel shoes. Sadie will sell each pair of heels for $60 and will purchase the shoes from a supplier for $30 per pair. The supplier has offered Sadie two shipping options: either (1) Sadie can pay $5 per pair of heels ordered or (2) Sadie can pay a flat shipping cost of $500 per month regardless of the number of pairs ordered. All of Sadies sales will be made online. The cost to maintain and manage her website will be $750 per month. In addition, Sadie will rent a small space to store inventory for $250 per month. Sadie does not expect any additional costs in her operations as long as she does not sell more than 150 pairs of heels per month. Which of the following statements is incorrect? A. If annual sales revenue is $54,000, Sadies operating income will be higher under option 1 than it is under option 2. B. Sadies monthly breakeven point under shipping option 1 is 40 pairs of shoes. C. Shipping option 2 is a riskier cost structure for Sadie. D. Sadies annual breakeven sales revenue under shipping option 2 is $12,000. E. At a monthly sales volume of 100 pairs of shoes, Sadie will be indifferent between the two shipping options.
